我在数据库表中有位置名称和位置ID.使用foreach循环我在PHP中的复选框中打印值.我有一个触发javascript的提交按钮.我希望用户在javascript变量中选择以逗号分隔的所有复选框值.我怎样才能做到这一点？

    <!-- Javascript -->
<script>
        function getLoc(){
                var all_location_id = document.getElementByName("location[]").value;
                     var str = <!-- Here I want the selected checkbox values, eg: 1, 4, 6 -->

            }
        <script>

foreach($cityrows as $cityrow){
echo '<input type="checkbox" name="location[]" value="'.$cityrow['location_id'].'" />'.$cityrow['location'];
echo '<br>';
}
echo '<input name="searchDonor" type="button" class="button" value="Search Donor" onclick="getLoc()" />';

我想通过其isbn数搜索书籍信息并检索信息并显示/存储信息的结果.

例如,我使用以下url
